Rook Toolbox

The Rook toolbox is a container with common tools used for rook debugging and testing. The rook toolbox can run as a deployment in a Kubernetes cluster where you can connect and run arbitrary Ceph commands. Launch the rook-ceph-tools pod and enter inside

Toolbox 
# The file is located in the folder "rook/cluster/examples/kubernetes/ceph"
$ kubectl create -f toolbox.yaml
# Once the rook-ceph-tools pod is running, you can connect to it with
$ kubectl -n rook-ceph exec -it deploy/rook-ceph-tools -- bash

Once inside the Pod you can check the status of the Ceph cluster with

Cluster Status 
# For the complete list of arguments use "ceph -h"
$ ceph status
  cluster:
    id:     ac25fc89-881e-419c-8596-be26252f8b92
    health: HEALTH_OK
  services:
    mon: 3 daemons, quorum a,b,c (age 93m)
    mgr: a(active, since 6h)
    osd: 3 osds: 3 up (since 6h), 3 in (since 6h)
  data:
    pools:   1 pools, 1 pgs
    objects: 0 objects, 0 B
    usage:   3.0 GiB used, 117 GiB / 120 GiB avail
    pgs:     1 active+clean

$ ceph osd status
ID  HOST                     USED  AVAIL  WR OPS  WR DATA  RD OPS  RD DATA  STATE

When you are done with the toolbox, you can remove the deployment kubectl -n rook-ceph delete deploy/rook-ceph-tools.
